Description

D-Alanine, n-Hydroxy-, Ethyl Ester (9Ci) is a specialized chiral building block and a derivative of the amino acid alanine. This compound matters for its role as a key intermediate in the synthesis of more complex molecules, particularly in pharmaceutical research and fine chemical manufacturing. It is primarily needed by researchers and process chemists in the pharmaceutical, agrochemical, and biotechnology industries for developing active pharmaceutical ingredients (APIs), peptide mimetics, and novel bioactive compounds.

Application

• Pharmaceutical Intermediate: A crucial chiral synthon for the research and development of new active pharmaceutical ingredients (APIs) and therapeutic agents.
• Peptide Chemistry: Used in the synthesis of modified peptides and peptide mimetics, where the hydroxy and ester functionalities allow for further chemical elaboration.
• Agrochemical Research: Serves as a building block in the design and synthesis of novel herbicides, fungicides, or plant growth regulators.
• Biochemical Research: Employed in enzymatic studies and as a precursor for probes or inhibitors targeting specific biological pathways.
• Fine Chemical Synthesis: Acts as a versatile intermediate for creating complex, high-value specialty chemicals with defined stereochemistry.
